飯後喝茶 影響消化易結石 【中新網】很多人習慣在飯後，馬上喝杯茶，認為這樣可以促進消化。實際上，這並不是個好習慣，它不僅會導致消化不良，還有可能增加患結石的風險，因此民間也有「飯後喝茶等於喝毒藥」的說法。那麼，這到底是什麼原因呢？ 生命時報報導，天津藥物研究院研究員李紅珠表示，「茶葉中含有鞣酸和茶鹼，這兩種物質都會影響人體對食物的消化。」胃液和腸液是人體消化食物必不可少的，可是當鞣酸進入胃腸道後，會抑制它們的分泌，從而導致消化不良。此外，鞣酸還會與肉類、蛋類、豆製品、乳製品等食物中的蛋白質產生凝固作用，形成不易被消化的鞣酸蛋白凝固物。需要特別提醒的是，如果吃的食物當中含有金屬元素，如鐵、鎂等，鞣酸還有可能與它們發生反應，長年累月就可能形成結石。 此外，胃酸偏酸性，而茶水偏鹼性，飯後立即喝茶，茶鹼不僅會抑制胃酸的分泌，還會稀釋胃酸，影響胃酸中蛋白酉每等的分泌，從而影響消化。有關實驗還表明，飯後飲用15克茶葉沖泡的茶水，會使食物中鐵的吸收量降低50%。茶水的濃度越高，對身體的危害越大。 去餐館吃飯，在飯菜上桌前，人們也不忘要杯茶水。李紅珠提醒說，飯前最好也少喝茶。如果要喝，應該選擇菊花茶等淡茶，但切記不能在吃飯過程中喝茶，這樣更容易導致消化不良。 那麼吃完飯後，我們應該喝點什麼呢？專家表示，白開水是最好的飯後飲品，即可清口又不影響消化，飯後過半小時就可以喝一些淡茶了。 2008-10-17 Easy to digest the impact of tea after dinner stone 【】 BEIJING, many people in the habit of meal, a cup of tea at once, so that can promote digestion.
